CHECK-ROW CORN=PLANTER.

SPECIFICATION forming part of Letters Patent No. 390,529, dated October2, 1888.

A pplioation filed March 16, 1888. Serial No. 267,864. (No model.)

To all whom it may concern.-

Be it known that I, NILs O. STARKS, a citizen of the United States, anda resident of Madison, in the county of Dane and State of Wisconsin,have invented certain new and useful Improvements in Check-RowCorn-Planters; and I do hereby declare that the following is a full,clear, and exact description of the invention,which willenablc othersskilled in the art to which it appertains to make-and use the same,reference being had to the accompanying drawings, which form a part ofthis specification, and in which Figure 1 is a perspective view of myimprovement. Fig. 2 is a side elevation of the same. Fig. 3 is a similarview at right angles to Fig. 2. Fig. 4 is a vertical sectional view onthe line mm, Fig. 2. Fig. 5 is a similar View on the line y 3/, Fig. 4;and Fig. 6 is a view of the sector as it appears when viewed from theinner and under side.

Like letters of reference denote corresponding parts in the severalfigures.

My invention has relation to mechanism for operating the seed-slide in acheck-row cornplanter of that class in which said slide is operated bymechanism actuated by means of a cord or chain provided with knots orbuttons in the well-understood manner. My'improvement, however, has norelation to that part of the mechanism which receives and again pays outthe knotted cord or chain at the side of the machine, but has relationsolely to the peculiar construction and combination of parts of thedevice, whereby a reciprocating motion is imparted to the seed-slide, aswill be hereinafter more fully described, and particularly pointed outin the claims.

In the accompanying two sheets of drawings, the letters A A denote theusual mechanism which receives the knotted cord or chain at the frontend and pays it out at the opposite end, the said cord or chain passingover the front pulley, B, then between the arms of the forked lever D,and then again out between the rear pulleys, C and E, where it leavesthe machine. The bifurcated lever D has its fulcrum at F, and isprovided with a bracket or projection, G, having a stud, H, upon which ared, I, is pivoted. The rear end of this lever D is connected by aspring, (I, to

the rearward end of the plate or bracket which supports the pulleys Band C.

Inasmuch as the several parts of this mechanism form no part of myimprovement, a further description of the same is not deemed necessaryin this connection, as its construction and operation will be fullyunderstood by all persons conversant with the art to which itappertains.

Upon the middle of the machine, midway the parts A A, is a verticalsleeve, L, the lower part of which forms a cross'head, l, and trunnionsm m, which are secured in suitable bearings or standards, J J.

Rocking sectors M M arcjournaled upon the trunnions, between theirbearings and the cross-head of the sleeve, which crosshead formsabutments for the sleeves of the sectors, as seen more clearly in Fig.4. of the drawings. The said vertical sleeve is supported by brack cts NN, bolted to any suitable part of the frame of the machine in such amanner that they will not be in the way of the rocking sectors duringthe operation of the machine. Through this central vertical sleeve orcollar L is inserted a shaft, 0, the lower part of which is providedwith a crank, P, having an adjustable wrist-pin, p, which is connectedto the seed-slide (indicated in dotted lines) in the usual manner. Theupper end of shaft 0, which projects above the sleeve, is provided witha pinion, 0, engaging a coggcd segment, Q, 011 the inner face of each ofthe rocking sectors M M. Each of these sectors above the aforesaidcogged segment is provided at each end with a beveled shoulder oroffset, R, and also with a flange, S, which said flange is bentinwardly, so as to form a cam, T, the point of which lies midway betweenthe shoulders RB and is flush with the inner side of the sector. Eachsector is provided with an arm, U, and asleeve, U, whereby it isconnected to its ap propriate trunnion m. When the rocking sectors areplaced in juxtaposition to each other, their inner flat faces will slideupon each other, and their upper rounded hearing, which is provided withthe shoulders or offsets R, will, by the cam-flanges S, form a groove orway adapted to receive the bent ends or shoes 2 1', whereby the rods I Iare connected to the bifurcated levers at the sides of the machine.

These bent ends or shoes 1' of the connectingrods I are bent inwardlyand pointed or rounded, so as to engage recesses r in the offsets orshoulders It, and said rods I, where they engage with the sectors, areprevented from becoming disengaged or slipping out of the groove inwhich they play by means of the bails or keepers V V, which are suitablyfastened to laterally-projecting ears of the central sleeve, L, whichsaid ears may also form means of attachment for the supportingbrackets NN.

At one end each of the rocking sectors is preferably provided with adownwardly-projecting guide-piece, W, overlapping the under side of theopposite sector and adapted to form a stop when it comes in contact withthe ends of the cogged segment Q opposite.

The operation of my device is as follows: When the machine is at rest,or in the position shown in Fig. 1, the inner ends of theconnecting-rods I I will rest with their shoest' iin the groove formedby the flanges S S between a pair of shoulders on opposite sectors. WhenU the knot or button strikes the forked lever and tilts it back, theconnecting-rod on that side of the machine will be pulled back againstthe shoulder or offset with which it engages, thus drawing theappropriate sector, of which this offset forms a part, with it, andtilting the sector to one side. This, of course, also tilts theappropriate cogged segment Q, and as this meshes with the pinion 0aone-half revolution is imparted to the vertical shaft 0 and the crank atthe lower end of the same, and whereby, again, the seedslide is operatedby pushing it to one side. After the cord or button, however, has becomedisengaged from its appropriate lever, the tension of the spring d willdraw it back into its normal position, whereby its connecting-rod I ispushed back, so as to release the shoe On the backward stroke of the rodon the way to assume its normal position the cam T, formed by theflanges S S, will guide the free end of the rod over upon the oppositesector, so as to bring it into engagement with its appropriate shoe 6 ofthe same, and thus at each reciprocation of the forked or bifurcatedlever its appropriate connecting-rod will alternately engage oppositesectors, and thereby rock said sectors alternately forward and back,thus rotating the pinion with which these sectors engage alternately inopposite directions. This movement not only operates to reciprocate theseed-slide, but as the pinion engages with both the sec tors the sectorwhich has just been released from the connectingrod is brought back intoits normal position by the pinion, ready toreceive the connecting-rod atthe next stroke of the machine. As both connecting-rods operateprecisely alike, it will be seen that the sectors will be actuated inprecisely the same manner, whether one side of the machine is in use atrest while the other is in operation.

As the rocking sectors, with their several parts, may all be cast in asingle piece, it will be seen that this device consists of but fewseparate parts, which are inexpensive in their construction, readily puttogether, and certain in operation, so that this improvement may bemanufactured at comparatively a small cost, and will prove not onlyabsolutely certain and effectual in use, but very strong and durable, sothat it is not apt to break or otherwise get out of order, even if themachine is subjected to exceptionally rough usage.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States- 1. In a check-row corn planter, thecombination of rocking sectors with the connecting-rods and bifurcatedlevers, whereby a reciprocating motion is imparted to said rods,substantially as and for the purpose shown and set forth.

2. The combination of the rocking sectors each provided with an arm anda sleeve, and also with a cogged segment on its inner side, the pinionengaging said segments, the pinion-shaft, and the crank at the lower endof the same for actuating the seed-slide, substantially as and for thepurpose shown and set forth.

3. The combination of the rocking sectors, the connecting-rods, acentral sleeve having ears upon its sides, and the bails or keeperssecured to said ears and straddling the sectors and connecting-rods,substantially as and for the purpose shown and set forth.

4:- The combination, with the rocking seetors having the studs oroffsets at their ends, and having the side flanges bent to form the camT midway between the shoulders, of the rods I I, the ends of which arebent inwardly and pointed, substantially as and for the purpose shownand set forth.

5. The combination of the rocking sectors having cogged segments Q, andeach having a downwardly-projecting guide-piece at one end, with apinion meshing with said segments, substantially as and for the purposeshown and set forth.

6. The combination of the central vertical collar having a cross-head atits lower end, the journals or pintles at opposite sides of saidcross-head, the rocking sectors provided with trunnions working uponsaid journals and having cogged segments on their inner sides, thecrank-shaft journaled in the central sleeve, and the pinion at the upperend of said shaft, adapted to mesh with the cogged segment,substantially as and for the purpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereuntoaffixed my signature in presence of two witnesses.
